The One Thing You Need Before You Have Sex With Someone

It's pretty easy.

Knowing to have sex with someone only if they want to have sex with you should be a no-brainer. But with 1 in 5 college women (and men, too) the victim of sexual assault or rape, too many people aren't getting it.

Thankfully, women's health care provider Planned Parenthood devised a string of videos that explain "Consent 101," in other words, how to know it's OK to have sex with someone — from checking in to see if the person is OK with what's happening to understanding body language — and they're much more real than the ones your university made you watch as a freshman.

Though it may seem self-explanatory, the lines can get blurred, but with the understanding of this one thing, they don't have to.

It's consent.

According to the video, "consent means that both parties are really, truly into what's going on. This means no one is being guilted or pressured into doing anything."

"Some people think it's not rape unless someone is fighting, screaming or someone yelling no. But that's not always the case," the host says.

He goes on to explain that body language is just as an important of an indicator if someone does or doesn't want to have sex as words. Pulling away, unconsciousness or generally not happy about what's happening, even if they themselves agreed to everything else up to that point, is not consent.

There's misconceptions that consent isn't sexy, but that couldn't be further than the truth. If anything, isn't sex more fun when both people actually want to do it?
